I saw one of these in a store and even as someone who's pretty unskilled on a sewing machine I figured I could make one pretty quickly as a present for my wife. If you already know your way around a sewing machine, that's probably the case. As for me... well, the next time will be faster.
Thanks to scoochmaroo for showing me what a zipper foot is.
Step 1: Get Zippers
Step 2: Start sewing
Step 3: Keep on going
Again, make sure that the zippers are lined up when you're putting them together.
The results should look like the two pictures below.
Step 4: Close it up
I know it's been fun so far, but now you can make scary looking zipper squids! Yeah!
Step 5: Sew the ends closed
Sew the ends up and your sewing is done!
Step 6: Turn it inside out
Poof! You're done!
Now that your need for making something has been satisfied, give it away as a present.
